EJECTOR FOR INSECT-POWDEFiS.

SPECIPICATION forming part of Letters Patent No. 297,693, dated April29, 1884.

Application filed November 8, 188d. (No model.)

The object of the invention is to provide an insect-duster consisting ofa powder-receptacle and a blower, in which the receptacle is providedwith'a screw-cap which connects with the receptacle at its largestdiameter, and to which is soldered a nozzle. This nozzle, extendingthrough the center of the cap, has a bayonet-connection with the nose ofthe bellows, and the portion thereof which projects within thereceptacle is perforated to emit jets of air under pressure in differentdirections into the receptacle, and thus stir up and disintegrate themass of powder,which is liable to pack closely in the receptacle. Thisconstruction provides for the ready filling of the receptacle through anaperture which is the whole diameter of the receptacle. A perforateddiaphragm prevents the powder from packing in and choking the dischargepassage or nozzle of the receptacle.

WVhat I consider the best manner of carrying out the invention is fullyillustrated'in the accompanying drawings, which form a part of thisspecification.

Figure 1 is a side elevation, certain parts being broken away to bettershow the construction. Fig. 2 is a central longitudinal section. Thereservoir is shown detached and turned into position for filling.

Referring to the drawings, in which similar letters of referenceindicate like parts in both the figures Adesignatesa cylindricalreceptacle, having one conical end, a, with a nozzle, a, as shown. Eachend is provided with a screwthread, a, which engages a similar internalthread in the cap'B or end piece, a. Projecting through the center ofthe end cap, B,

is a nozzle, 0, which is secured to the properly-tapered wood nose D ofa suitable bellows, F, by a bayonet-joint at c. The portion of thisnozzle 0 which projects within the body of the powder in the receptacleA is perforated at several different points, as seen at c, to provide amultiplicity of jets of air,which serve tostir 'up the powder. Aperforated diaphragm, E, is located in the portion a of the receptacle,and serves to prevent the powder from packing in the nozzle a. I providea valve, f, of leather or other cheap and durable material, secured by ascrew to the wood of the bellows-nozzle D. This prevents the powder frombeing drawn backward into the bellows. The receptacle, as thusconstructed, allows the ready insertion of the powder by detaching thereceptacle from the bellows, by detaching nozzle 0 from nozzle D, or,preferably, by the removal of the cap B, to which is secured by solder,at b, the nozzle 0. Either method gives a large opening to receive thepowderrapidly and without scattering it. When the device is in use, themultiplicity of jets of air from the apertures c agitates the powder,however it lies. r

I provide exchangeable tips a, which are connected to the conical end a.by screw-threads. Whenever desired, the tip a maybe unscrewed from itsconnection with the nozzle and a new one substitutedhaving a'dift'erentsize or a different form of discharge-orifice. One advantage, due to thetips a being conveniently detachable, is the facility it affords foremptying them. There is always aliability, particularly with thefinest-pointed tips, that sufficient powder will get past the diaphragmE to clog them. In such case they are readily unscrewed and emptied.

I do not confine the invention to the use of insect-powder, strictly socalled, or to its use ininjecting powder into cracks and recesses inbuildings and furniture. I can supply parisgreen or analogous materal ina powdered c011- dition to the reservoir and use a large nozzle for thedischarge anddust powder upon the surfaces of plants in the fields, orin various other situations where a powder is to be dis-. tributed.

I claim as my invention- In combination with a readily-detachable myhand, at New York city, New York, this current-inducing means, as F D,and a pow- 29th day of October, 1883, in the presence of der-reccptaclehaving athread, a the cap B, two subscribing witnesses.
